Abstract
Thermally decomposed in a sealed thermal chamber, were subjected to oxide-nickel and iron electrodes of nickel-iron batteries: ТЖН-250-У2, ВНЖ-250П-У2, ТНЖ-350-У5. It was determined that visible release of gas starts at about 400 °С for the iron electrodes and at about 600 °С for the oxide–nickel electrodes. Main decomposition was performed at 8000С. Gas was on average 98 % of hydrogen, 1,5 % of oxygen and 0,5 % of other gases. Moreover from oxide-nickel electrodes, on average, was released 1,5 times more hydrogen than from iron electrodes. It was shown that in electrodes of nickel-iron accumulators having long periods of operation there is a great amount of hydrogen. For example, in the accumulator ТЖН-250-У2 having a ten year’s period of operation there are approximately 9700 litres of hydrogen.
Keywords: battery; nickel-iron; hydrogen accumulation; thermal runaway.
